New: talk to it. Ask by voice, type, or share a photo and get answers right on your iPhone. No internet, no account, and your conversations never leave the device.
ThinkByte is an AI assistant that runs on your iPhone instead of in the cloud.
Ask it a question, talk to it, or show it a photo, and it answers right on the device. Nothing connects to a server, so it works the same on a flight, on the subway, or anywhere with no signal. Your conversations stay on your phone and are never uploaded.
Type or talk.
Use the keyboard, or hold the mic and speak. ThinkByte takes voice and images, not just text.
Choose your model.
Download a small, fast model or a larger one for tougher questions, right from the app. More get added over time.
Private by default.
No account. No sign-up. Your chats never leave your phone. Anonymous diagnostics are optional and you can turn them off in Settings.
Built for real life:
Flights and travel
Subways, basements, and dead zones
Limited or expensive data plans
Anyone who would rather keep their conversations off other people's servers
Download ThinkByte and start chatting, fully offline.
You can talk to it now. Hold the mic and speak, send a photo to ask about it, and switch English/Arabic instantly. All on-device.
More in this update:
- Faster voice input that starts the moment you hold the mic.
- Ask about a photo. Share an image and get answers, all on your device.
- Instant English and Arabic switching, no restart.
- A cleaner model screen, plus chat scrolling and keyboard fixes.
